Reducing Real Tag format

[warren]

Hello,

I have some real tags that I need to illustrate on the HMI. These are global data block “real” on my PLC, and transferred as an OPC tag into Ignition, displayed on a basic textbox:

These appear in the tag browser as one number, but when I click on the tag itself, it actually shows a much longer string of numbers like the textbox. How can I make the textbox reflect the reduced value in the tree?

Use a Numeric Text Field component and modify its Decimal Format property if the default is not suitable.

the reduced value

For future reference, this is "rounding", not "reducing". Due to the quirks of binary numbers in floating point, this is almost always required at the point of display.
